IMPROVEMENT IN WIND-MOTORS.

Specification forming part of Letters Patent No. 173,368, dated February 8, 1876; application filed october r2, 1875.

To all whom it may concern.:

Be it known that L-GEo. S. STRONG., of Springeldin thecounty of Clarke and yState of Ohio, have invented a new and valuable Improvement in Wind-Motors; and I do hereby declare that the following is a full, clear, and exact description of the construe` tion and operation of the same, reference being had to the annexed drawings, making a` part of this speciiication, and to the letters and figures of reference marked thereon.

-present invention are, iirst, to employ, below the Vanti-frictionI collar, an anti-friction turntable, which turns on the bottom of a suspended cup or cap, for the purpose of giving steadiness to the mill, as will be hereinafter explained; second to provide for holding the i' wheel to the wind by means of a spiral spring arranged inside of tubes which telescope, the power of resistance of which spring will in` crease as the vane is moved around toward the wheel, thereby compensating for the in crease of leverage which takes place as the wheel is thrown oi' the center.

In the annexed drawings, A designates the tower of the mill, on the platform a. of which a cylindrical cup, B, is rigidly secured by means of bolts passed through its iianges. O designates the vertical shaft of the mill, and D is a circulariianged cap, which is rigidly secured to said shaft and supported on antifriction balls c, applied within an annular flange, d, cast on top of the cup B. The flange d around the cap D is outside of the flange d, and between the iange d and a cylindrical hub, c, on the cap D, the balls c are applied. By these means the lateral friction so common in many wind-mills, is avoided.

The shaft G extends down through the bottom of the cup B, and just above this bottom is a circular turn-table, f, which is supported upon anti-friction balls g. A steady motion without vibration is thus obtained. E designates a fram-e, which is on the cap D, and h designates a long tubular'bearing, in which turns the shaft of the wind-wheel F. On the inner end of the wheel-shaft t' a crankwheel, j, is keyed, to the wrist-pin of which the lower end of a pitman-rod, G, is pivoted. The upper end of this rod has a socket formed in it which receives a ball on the upper end of a hollow working-rod, EI. The pitman G plays through an oblong slot made through the frame E, and the rod H plays through a hole alongside of the said slot and also through the center of the shaft G, as shown in Fig. 2. The ball-and-socket joint j, which connects the two rods G H together, prevents binding under all circumstances. Kdesignates the rudder-vane, the shank 7c of which is connected to the frame E by a vertical pivot-bolt, n, To the lower edge of the rudder-vane shank lc a rod, lm., is pivoted, which is acted on by a spring, p, inclosed in a case, r. rIhe case r passes through a bracket, t, to which it is pivoted by vertcal'pins that allow it horizontal vibration.

The regulating-rope s is fastened to an eye fixed to the shank k and passed around pulleys t o, thence carried down through' the workingrod H. The wheel F is composed of radial blades, suitably feathered and secured to rings concentric to the axis of the wheel. The said rings are rigidly secured to radial arms N, which are made hollow for the purpose of ai'ording lightness.

What I claim as new, and desire to secure by Letters Patent, is

-1. The collar D, having a ange, d', in combination with cup B, provided with flange d, turn-table f, balls c g, substantially as described, and for the purpose set forth.

2. The spring p, iucased substantially as described, in combination with the pivoted rudder-vane and the cap D, asset forth.

In testimony that I claim the above,`I have hereunto subscribed my name in the presence cf two witnesses.

GEO. S. STRONG.
